Application led April A19, 1920.` Serial No. 375,156.

To all 'whom t may concer/n:

Be it known that I, 'CORNELL FLAe'sTAD, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have ,invented a new and useful Box-Cover andk Fastening for Same, of which the following is a specification.

My invention relates to box covers and fastening means for same. The main object is to provide shipping boxes and crates with an improved cover and means for holding such cover latched, and also sealed if so de sired. l

In the accompanying drawing:

Figure 1 is a top view of a box equipped with my improved cover and Jfastening. Fig. 2 is an enlarged section on the line 2-2 in Fig. 1. Fi 3 is a modication of Fig. 1. Fig. 4 is an en arged section on the line 4-4 in Fig.'3. Fig. 5 is adetail top view of the lower part or member of the catching and lockinv device with the element 29 in Fi s. 6 and? omitted. Fig. 6 is a section on t e line 6-6 in Fig. 5. Fig. 7 is a detail top view of Fig. 8. Fig. 8 is a right hand end view of the element 29 in Fig. 6.

Referring to the drawing by reference numerals, 9 designates a box or crate of which only the top portion is shown. Two opposite sides, or ends of the box may be a little higher than the other two sides, so that the cover 10 passes down between the highest sides 11 and rests upon the two lower sides 12, as indicated in Figs. 1 and 2, but this is no essential feature of the invention.

The cover is divided in they middle into two sections 13, 14, which are attached together by two hinges 15, and may also have a third hinge 15, as in Fig. 3. Each section has its outer edge supported by a strip or ledge 16 secured in the box, andy close by the top of said ledges the sides 11 are provided with apertures 17 or it may be sockets or cavities like 17 a to the left in Fig. 4.

When the cover is put in place on the box, two fiat ingers 18, fixed on each cover section, engage in the sockets 17. In order to so engage and likewise to disengage the iingers, the middle of the cover is raised as shown in dotted lines in Figs. 2 and 4, or as much higher as may be necessary.

When the cover is put on and in plane position it is latched or locked down by any suitable catch that will answer the purpose, but as such catches may be of several forms I will simply indicate their nature showi ing acover securing device, for which I have already secured Letters Patent. Said device is clearly shown in Figs.` 5 to' 8. It consists of a metal plate 19 securable by rivets or like means 2O up'under the cover section 14,V

or in Figs. 3 and 4 up under an undivided rigid board 14 of the cover.

Slidably inserted in the angular ends 21 of the plate and in guides 22, is a slide 23 having at one end a finger catch 24, and at the other end hooks 25 to limit the action of a spring 26, which at all times tend to move the slide as Jfrom right to left in Figs. 5 and 6, and thus cause its solid portion 27 to move into a notch 28 of a bracket 29. Said bracket has also an aperture 30 adapted to receive a wire or metal strip 31, whose ends may be secured in a seal-lock 32. The bottom end 33 of the bracket extends horizontally and is secured by screws 34 to the underside of a board 35, having a slotted hole up through which the body of the bracket extends and engageswith the slide of the member secured to the cover.

In Figs. 1 and 2 the board 35 is loose and carries only the bracket 29, but evidently the cover ycannot rise in the middle as long as its slide 23 is engaged with the bracket in an unbendable board underneath the cover, In Figs. 3 and 4 the cleat 36 carries the bracket 29 and the jointless board 1421 carries the plate 19 and its slide 23. It will be observed that said board 14EL or rather 13a14a is not secured to the cleats 36-37, but only to the cleats 38-39, while the rest of the boards in the cover are secured at 40 to all of said cleats. In Figs. 1 and 2 the cover boards are secured at 43 upon cleats 41 and 42. The hinge 15 in Fig. 2 is secured up under cleats 42 (beyond the board 35) and the prongs 18 are also secured to the undersides of the cleats. This is true of both cleats, 36, 39, 41 and 42. 44 is an aperture in the cover'for reaching the locking device to operate it.

, rests with its ends uponthe ledges 16 and With the structure thus described the cover is as firmly and reliably secured in place as i screwed or nailed down, and yet it is attachable and detachable in a moment andA without tools, except .for opening the seal in the case where a seal is employed.

What I claim is:

1. The combination with a box or crate having some distance below its top sockets iio in two opposite sides, of a cover havin iiXed at its under side projections adapte to enter into the sockets, said cover being divided near its middle into two sections and having upwardly bendable hinges conneotng the adjacent edges of the sections, thusmaking the cover bendable upward at the joint of the sections, means for supporting the cover in plane position and means for locking it in plane position on the box so it cannot bend upward Aat the joint.

2. The structure specified in claim l', and

`means for sealing the locking device.

3. The structure Specified in claim l, said locking means composed of two interlocking parts, one part'carried by the cover and accessible for operation through an aperture in the cover the other composed of a catch and an unbendable lat bar fixed thereto and arranged underneath the cover.- S-

4. The structure specified in claim 3, said unbendable flat bar being secured to the underside of the cover. j

. In testimony whereof I ath; myisignature.
